What is the difference between Traditional RAN and Open RAN?
April 16, 2021

Open and virtualized RAN, Open vRAN refers to a disaggregated approach of deploying virtualized mobile networks by using open and interoperable protocols and interfaces, implemented over a common propose hardware in a multi-vendor software environment, allowing increased flexibility over traditional RAN architectures., aiming to provide OPEX and CAPEX savings while fostering innovation. Traditional RAN Protocol […]

What is the difference between 4G Core and 5G Core?
April 15, 2021

In LTE Core Network, all data plane traffic must go through a single node type called Packet Data Network Gateway (P-GW). This centralized architecture is advantageous in terms of operation and management. Yet, it could potentially pose a severe limitation when there is a huge amount of backhaul traffics in 5G. The following figure illustrates […]

Functional Split Options for 5G Networks
April 5, 2021

Functional Split Options for 5G Networks As network architects work to meet the 5G challenges of increased traffic and data flows, a fundamental question is how much intelligence to put near the antenna versus at the DUs or CUs. Mobile Network Operators (MNOs) as well as industry-standards groups, such as the 3GPP, IEEE, Telecom Infra […]

Function Migration from 4G to 5G
March 10, 2021

5G shouldn’t be seen simply as the next generation of mobile communications. It’s a smart ecosystem that’s ready to catch new innovations and highly customized services. 4G to 5G Interworking 4G LTE and the 5G networks will continue to interwork for a number of years. This is why it’s essential to:  Support a seamless handover […]

Why do MNOs struggle to shift to Open RAN?
March 7, 2021

Why do MNOs struggle to shift to Open RAN? I know many MNOs are struggling to shift their RAN strategy to OpenRAN in their 5G Roadmap due to many reasons like they can not get away from their monolithic supply chain from the big vendors. Also, there’re some interfaces that are still NOT open even if these […]

What Determines The Capacity Of A Network?
February 17, 2021

In the early 1900’s two researchers working independently derived a relatively simple equation that serves as a Moore’s Law for the wireless industry: the Shannon- Hartley theorem. This theorem gives an upper bound to the amount of information that can be transmitted over the wireless channel where the individual channel capacity is dependent on only […]

What is RAN Disaggregation?
February 16, 2021

In the cellular network, RAN provides wide-area wireless connectivity to mobile devices. Towards this end, it conducts two fundamental tasks: It converts IP packets to Physical Layer packets suitable for transmission over the time-varying mobile channel using packet and signal processing techniques. It conducts Radio Resource Management (RRM) control to determine how best to use […]

Does 5G Icon on Your Phone mean Real 5G?
February 12, 2021

Some friends asked me, Should we have a 5G good data rate when seeing 5G Icon on our phone? Mmmm… My answer should be Yes, However it’s the not right answer as there’re many technical items we need to discuss first before answering this question.  Let’s remember this famous incident/debate from US company AT&T when […]

5G Voice Service Solutions
February 7, 2021

In June 2018, as 3GPP announced that the standalone (SA) standards have been frozen, the standardization of 5G Core (5GC) is complete. 5G network commercialization has begun and the world-wide mainstream operators are dedicated to 5G network construction. According to 5G deployment options, 5G voice solutions not only include the target solution Voice over New […]

5G New Radio (NR) Release 15 Technologies
February 3, 2021

  5G New Radio (NR) 3GPP is defining 5G NR in Release 15, with an initial release for a non-standalone operation scheduled for March 2018 and a full release for a standalone version scheduled for September 2018. 5G New Radio Release 15 Focus: 5G NR Release 15 features: Ability to operate in any frequency band, […]

5G Commercial Network in Gulf Countries
February 2, 2021

The Gulf Countries (UAE, Saudi Arabia, Qatar, Kuwait, Bahrain, and Oman) are the front runner in the 5G Race. They started to think of 5G as early as Mid-2019. Use Cases: The main initial two uses cases are eMBB (Mobile) and FWA (Fixed Wireless Access). 5G Spectrum Band: The 5G Spectrum Auction is in two […]
